Newly engaged Hayden Panettiere says the tattoo running down her back, Vivere senza rimipianti, is Italian for "Live without regrets," except, oops, the third word is misspelled. It should be rimpianti.

One thing is for sure: She won't regret posing for the cover of Glamour's swimsuit May issue, where the Nashville star explains she's not like the diva she plays on TV, and confides her love for her fiancé, her future children, her parents and country music.

Just don't mistake her for a role model, and not just because she plays conniving country singer Juliette Barnes on Nashville. She calls her generation of young Hollywood the "Messy Generation, the generation of the disaster child."

"I will never say that I'm perfect; I will never pretend to be perfect," Panettiere, 23, tells writer Lauren Brown. "That's just unrealistic. You're kind of unexpectedly put in this position of becoming a role model; that's not something you choose."

Other excerpts:

How does she feel about kids? "I was born to be a mother," she says. "Motherhood is the most beautiful, exciting thing, and there's nothing that I feel like I can't accomplish while having children in my life."

Could her fiancé, Ukrainian boxer Wladimir Klitschko, be a future father of her kids? "It wouldn't shock me!"

How did they meet? "An acquaintance of ours did a coffee-table book, and the proceeds went to genocide prevention. We met at the party for the launch of the book; we've been friends for five years — we've never not been close."

How did her parents' messy split (dad was arrested for hitting mom in 2008) affect her? "My parents are really good people — they just are not meant to be together."

Still, they helped ground her growing up. "I had friends and family around me to yank me back when I was heading in the wrong direction."

How has Nashville helped her singing career now that she's hit Top 40 charts with the show's Telescope? "I don't look at it as a second chance; I look at it as where I'm supposed to be. Even if I'm not perfect at it, even if my voice takes work, this is where my heart is."
